Will Seam 3.0 have this secure pages feature from Seam 2.2? There is no documentation from Seam 3.0 currently and from the sourcecode/api it seems like a lot of goodies from Seam 2.x is dropped in favor of PicketLink's bloated features.

That's just one way to provide it. We'll also see if we can get integration with PrettyFaces, or whatever navigation system we end up working into Seam 3. We couldn't focus on this any earlier as Seam Security wasn't ready. Now that it is, game on ;)
